Configuring IPv6 Multicast Source Port Filtering
With the IPv6 multicast source port filtering feature enabled on a port, the port can be connected with
IPv6 multicast receivers only rather than with multicast sources, because the port will block all IPv6
multicast data packets while it permits multicast protocol packets to pass.
If this feature is disabled on a port, the port can be connected with both multicast sources and IPv6
multicast receivers.
